This invention relates to improvements in guns and" more particularly to shotguns to other types of guns.-

n improved double barrel gun of the under? ndeover'type. a v H i According to one featureof this invention, as-applied .to' a double barrel gun of this io type, we provide an] inertia weight which carries the percussion ins, sears therefor, locking bolts and accumulator springs, the arrangement being such that relative moveinentbetweenthe. said pins and the inertia weight due'to' the recoil of the gun,,auto.-

matically effects the cooking of the said pins; a v

Preferably the arrangement is such that thepea-k of the recoil is reducedby the action oflthe inertia weight. I

"In'one form of construction we provide van inertia .weight slidably mounted in a recess" in. rear of the act-ion body. The weight .when under recoil floats, between fsprings, those at the rear of 'tlie'inertia weight extending during recoil and acting I'ias'buflersprings, whilst those acting on the frontffunction as accumulator springs. The forward end, of the accumulator springs I bear; against the locking bolts which lock so that these barrels remain closed solong asfl anyrecoilpbtains. is

.gr-o ecave the accumulator springs and the 5, locking bolts andalso; carries the secondary sears".- and theipercussion pins, which; when "the trigger'is released, impart a blow to fi ringpins. a I e '40)}; The secondary sears-are arranged verticallyand are slida-bly mounted at the rear oftheinertia weight, and are at right angles j-tO the. percussion pins, the said sears being locatedby :a plate secured to the inertia eight; The secondary sears are each nor spring housed 'on top ofthe weight whilst 'Sthe lower ends lof the secondary sears are .gsears, other ends of whichare engaged .although of course the'invention may apply a One Iobjectof our-invention is to provide the barrelsin positioin on the action body,-

the effective lengthof the spring and con- Accord-ing to a further feature of our Y invention which is 'notconfinedl to double barrel guns'of the uncler and-over type,-we provide the inertia weight. with locking means (additional to the' normal v locking means) for locking the barrelor barrels of the gun, the arrangement being such that on. recoil the said locking means is moved into. effective'loclringposition bythe relative movement between the gun I and the inertia weight. This may be effected by detachably securing to the inertia weight a cover plate.

which normally, overlaps the barrel. this latter being preferably slightly coned or bevelled so that when the gun; recoils,i'the cover further overlaps and comes into effective V engagement with the inner end of the barrel and prevents upward movement thereof.

A further feature. of our invention relates v tomeans whereby the costkofmanufacture V I I I ofa drop-down guncanfbe reduced. The-; nert1a; weight'is recessed. or bored According to this feature of our invention the breech end of the barrel or barrels is ily, and therefore more cheaply, bemore accurately shaped than isf-thecase' where tl 1e guiding' surfaces areintegral with. the

action body.

"In order'to break the gun, we provide a-lever having a projection which is adapted.

to bear against a lug securedf to the action body. The saiddeveris mountedon the inertia weight 7 and must" therefore partake of the to and fro movement duetofrecoil.

Due to the firing of the cartridge, tllGjlSLCliiOll body r'ecoils and the inertia -Weight 1 remainswstationary. 'Duringfthe recoil of the action body, the percussion pin of the recoil of the-actionbody then rocks the segment about its pivot 40- Wherebythe projection 42 on the segment completes the "movement of the percussion pin into the position shown in Figure :11, in which p0 j sition the secondary sear is pressed by thespring 23 into cooking engagement with the pin 12. It Will be seen that the segment.

38 moves the -percussion pin 12 approximately twice the distance that the action bodyinoves relatively to the inertia-Weight, the parts being so' arrangedfthat the percussion pin is moved so as .not to project beyond the face of the "inertia weight. The

percussion'pin 11, when it 'is' freed from its sear to fire the second cartridge, is similarly moved due to the recoil, by its segment 37,

and thus it will be seen'that percussion pins 11, 12 are automaticallycocked'by the recoil,

and. when int-heir cocked positions, the per-A cussion pins are in such position thatwhen one cartridge isiir'edythe other cartridge is not fired by the recoil ofthe'action body relatively tothe inertia Weight;

7 vWhen the action body'recoils relatively to the vinertia Weight 1, the projection {17 on the barrel body is'move'd into-binding engagement with the bevelled end of the cover plate 46, and thus-the breaking of th gunis prevented. i I

' It will be seen that a siiiiultaneous" firing of both cartridges, due to involuntary pull, 'is furthermore prevented by the separation of the primary sears from the secondary sears, owing to the recoil."

The accumulator springs 8'store part of i the energy of recoiland' expend this energyin returning the action body to its normal, position, the spring acting as; a buffer spring. v I
